Just as 60,000 foot high thunderstorms are known as airplane disassembly factories, I suppose a CAT 4 hurricane would qualify for an ocean ship disassembly factory. Smart pilots that like living don’t fly into thunderstorms. I don’t know about ship captains.
On Wednesday morning it was a tropical storm. On Thursday afternoon it was a CAT4 hurricane.
In 36 hours it rapidly intensified from a storm to a Cat4 hurricane.
